Title: Gate circuit for gate turn-off thyristor
Inventor: MOTOBE MITSUSACHI
IPC: H03K17/732
Filed: 1981-09-24
Abstract: PURPOSE:To reduce gate losses remarkably and to make the circuit constitution small in size, by splitting a switching circuit controlling a gate current of a gate turn-off thyristor into that for off-period and for tail-period. CONSTITUTION:A switching SW circuit controlling a gate current of a gate turn-off thyristor GT01 is constiuted with an SW element 4 for off-period, an SW element 7 for tail period, and a resistor 8 in parallel. The element 4 is turned on with signal (b) from a control circuit 5, a signal (c) turns on the element 7, a collector current (d) of the element 4 flows and an off-gate current (f) is applied to a GT01 via a pulse transformer 3. When the GT01 turns off and the element 4 is turned off, a collector current (e) of the element 7 flows, the gate current (f) is limited at the resistor 8, and since the gate current for the compensation of a tail current Itail only flows, a gate loss (h) is remarkably reduced, the elements 4, 7 can be made small in size and the circuit constitution can be made small in size.

Title: Sentence display device for copying machine
Inventor: YAMAGUCHI JIYUNICHI
IPC: G03G21/00
Filed: 1983-08-18
Abstract: PURPOSE:To enable easy display of the entire sentence for display by displaying successively the sentences by using an address selecting means 15 when a sentence inspection mode is set. CONSTITUTION:When the operator pushes the start key 44 in an operation board 24 in a sentence inspection mode, the count value is counted up by the number alpha at which the key 44 is pushed. A CPU28 reads out the count value of an address counter 36 for output sentence and reads out the character code array of the corresponding address from an ROM32 for storing sentences. A character generator 35 generates the character pattern complying with the character code array and displays the same on a character display tube 39. In other words, the character code array stored in the ROM32 is successively read out and displayed on the display tube 39 at every push of the key 44. The entire sentence for display is thus easily displayed.

Abstract: PURPOSE: To eliminate a wasteful generation of heat, by means of controlling a base current of the transistor in the oscillating circuit in accordance with a level of the load, to provide an operational condition with its efficiency always near the highest.  
     CONSTITUTION: If closed a switch 10, a current is supplied to the base of a transistor 1 and 2 through a resistor 11 from a DC power source 9, with an oscillation started. And during the period until a regular output voltage is reached, a variable resistance element 18 is being held at a minimum value by an output signal of voltage detector 17. In a short time, with a regular output voltage given, the variable resistance element 18 will be controlled at an optimum level in accordance with a level of the load. If the load increases, the output voltage slightly goes down,  causing its detected signal to lessen the variable resistance element 18, resulting in  an increase of the base current for the transistor 1 and 2, and an action will work  to return the output voltage to the former level with a stabilization restored to at  the optimum value.

Title: Labelling system for picture data
Inventor: SATO MASAHIKO
IPC: G06T7/60
Filed: 1987-06-18
Abstract: PURPOSE:To attain the real time processing by operating a label revision means and a connection relation detecting means repetitively so as to apply high speed labelling till a new connection relation cannot be found out as to a labelled data. CONSTITUTION:An initial labelling means 1 uses a mask 100 with initial label to apply labelling to an input binary picture. A connection relation detection means 2 uses a connection relation detection mask 200 to check the connection of different label and stores the information to a connection table. A label revision means 3 revises the label by using the information. According to the label conversion rule at the detection of relation of connection, when a value of a label of a noted picture element is smaller than a maximum value of the label of four nearby picture elements in the relation of rotational symmetry, the label of the noted picture element is related into the maximum label. Till the detection of connection is not found out, the connection relation detection means 2 and the level revision means 3 in interlocking therewith are operated repetitively. Thus, the labelling is implemented efficiently at a high speed in this way and the real time operation is attained with a picture processing unit.
